Processors
Processors are located on the top and bottom surfaces of the processor extender board.
WARNING
Ensure that the system is powered down and all power sources have been disconnected from the server
prior to removing or replacing a processor.
Voltages are present at various locations within the server whenever an AC power source is connected.
This voltage is present even when the main power switch is in the off position.
Failure to observe this warning could result in personal injury or damage to equipment.

Installing Processors

CAUTION
Ensure that the cache size is identical for all processors. Failure to observe this caution will result in system
